Engine Oil Viscosity


 

Question:

Dear Kevin,

My name is Dan. I am an amsoil dealer. I was at a county fair and a guy came up to me, must have thought I needed an education. He said that oil gets thicker in viscosity, When it gets hot, because the molecular makeup. WHAT is this guy saying? He said that is why multi- viscosity oil has two numbers. I was told by another, that the viscosity rating is based on the gaps in the engine crank bearings. This came about by racers having there engine tested by engine manufactures. Can you shed some light on this for me. Personally I think their full of it.

The first guy is right ! Your engine needs the thinner oil when it’s cold and the thicker oil when it’s hot. They do have additives that make the oil thicker as the engine heats up.
